CROSS-REFERENCE TO RELATED APPLICATIONS

This nonprovisional application is a continuation application of co-pending U.S. patent application Ser. No. 15/581,795, filed Apr. 28, 2017, and entitled “SYSTEM AND METHOD OF PROVIDING A PLATFORM FOR MANAGING DATA CONTENT CAMPAIGN ON SOCIAL NETWORKS,” which is herein incorporated by reference for all purposes.

FIELD

The present invention relates to a system and method of providing a platform for managing a campaign for publishing data content on social networks.

BACKGROUND

Social networks have emerged as major platform for communication over the years, with hundreds of millions of interactions created by users every day. Marketing experts have long recognized that an effective marketing strategy must include a presence on social networks. For many corporate users that desire to post data content (also referred to as content data or content herein), one of their goals when broadcasting content (e.g., messages) is to capture the attention of a large number of audience members on these social networks so that such audience members may react to the posted content. The likelihood that audience members react to posted content may differ depending on various factors such as location, daily and weekly behavior patterns, time zone and volume of other content competing for the attention of the audience members. To address this, Lithium Technologies, Inc. developed a technique or system to formulate a user's schedule for broadcasting content on a social network, in order to increase audience members' reactions. “When-To-Post on Social Networks,” Spasojevic et al., Association For Computing Machinery 2015, which is incorporated by reference herein. While the system described in Spasojevic et al. is effective for its intended purpose, it would be advantageous to provide improvements to this system.

DETAILED DESCRIPTION

Embodiments of the present disclosure are described herein with reference to the drawing figures.

FIG. 1 depicts a block diagram illustrating an example system 100 of providing a platform (200 below) for managing a campaign for publishing data content on social networks. One goal of this campaign is to increase audience reaction to published or posted content. The content may comprise one or more items associated with a URL linking an item to the specific content (e.g., article) as known to those skilled in the art. In this embodiment, system 100 includes a central system 102 that communicates with content sources 104 such as social networks including Twitter, Facebook, Google Plus and others known to those skilled in the art via network 106. Network 106 is the Internet, but it may be other communication networks such as a local area network (LAN) or both the Internet and LAN as known to those skilled in the art. System 100 also includes one or more clients 108 that enable users to communicate with social networks 104 and central system 102 via network 106 by cable, ISDN, WIFI or wireless carrier networks as known to those skilled in the art. (Data and information are used interchangeably in this disclosure unless otherwise noted.)

Central system 102 incorporates platform 200 for managing a campaign for publishing data content on social networks (described below). Platform 200 incorporates several computer software modules and databases as described in FIG. 2 below. Central system 102 includes one or more servers that may be connected together through a network such as a local area network (LAN) as known to those skilled in the art. The one or more servers may include a web server as known to those skilled in the art. Each server includes several internal components (e.g., processor, memory, drives, etc.), databases, operating system, software modules and applications (e.g., browser) as known to those skilled in the art. An example server is described below.

Content sources 104 are a system of one or more servers that comprise any number of social networks (herein after also referred to as social networks 104). Social networks 104, as known to those skilled in the art, are typically web-based systems that allow users to create a profile, post content, connect to other users, react with posted content and create a list of users with whom to share such content (e.g., social media data). Users of social networks may refer to users that post content or users that react to the content, i.e., users' audience members. Reactions to posted content are also referred to herein as interactions or engagements such as likes, favorites, clicks, user shares, comments and other reactions. The content may be photos, videos, articles or any other information and/or links linking to such content. Examples of social networks 104 include LinkedIn, Twitter, Facebook, Google Plus as shown in FIG. 1 as well as Instagram, Pinterest and Tumblr (to name a few). These web-based systems may also include a web server. Each server includes several internal components (e.g., processor, memory, drives, etc.), databases, operating system, software modules and applications (e.g., browser) as known to those skilled in the art.

Content sources 104 may also include a system of one or more servers that comprise news or other sources of information that provide RSS feeds to enable users to access such information as known to those skilled in the art as well as any number of events, articles, PDFs, videos, photos or other (together “articles”) that users may access via a URL (uniform resource identifier) posted on social networks 104 that link to such articles as known to those skilled in the art. The one or more servers may include a web server as known to those skilled in the art.

Clients 208 include laptops, personal computers and mobile devices. The personal computer includes several internal components (e.g., processor, memory, drives, etc.), operating system, databases, software modules and applications (e.g., browser) as known to those skilled in the art. The mobile devices as known to those skilled in the art could be smartphones, cellular telephones, tablets, PDAs, or other devices equipped with industry standard (e.g., HTML, HTTP etc.) browsers or any other application having wired (e.g., Ethernet) or wireless access (e.g., cellular, Bluetooth, IEEE 802.11b etc.) via networking (e.g., TCP/IP) to nearby and/or remote computers, peripherals, and appliances, etc. TCP/IP (transfer control protocol/Internet protocol) is the most common means of communication today between clients or between clients and central system 102 or other systems (i.e., one or more servers), each client having an internal TCP/IP/hardware protocol stack, where the “hardware” portion of the protocol stack could be Ethernet, Token Ring, Bluetooth, IEEE 802.11b, or whatever software protocol is needed to facilitate the transfer of IP packets over a local area network. Each client 108 may access the Internet directly or through a network of one or more servers that communicates with Internet as known to those skilled in the art.

As shown in FIG. 2 , central system 102 incorporates platform 200 for managing a campaign for publishing data content on social networks (described below). In brief, platform 200 is a framework that enables a user to determine optimal time to post content (e.g., a message) within a specified time period in order to maximize the probability of receiving reactions from audience members. Platform 200 performs user personalized schedule generation including estimating audience reaction, domain specific schedule personalization (tuning) and user strategy for scheduling multiple posts. Platform 200 performs all of the collection of the data from the social networks, processing of such data and posting of such data on the social networks. This is described in more detail below.

Platform 200 for managing a campaign for publishing data content on social networks comprises computer software modules and databases including campaign user interface module, 202, identity managing module 204, content discovery module 206, scheduling module 208, security-authorization and approval module 210, data analytics engine module 212, user account database 214, content database 216 and schedule database 218.

Campaign user interface module (UI) 202 is a user (who desires to post content) interface as known to those skilled in the art, that enables a user to engage with platform 200 to select content for posting and time parts for such posting. For example, module 202 enables user to (1) use a calendar to set a date and time (day parts) for posting content, (2) select content discovered or user selected, (3) select social networks in which the user desires to post such content and (4) review data metrics of all data computed (e.g., reactions and the audience members) by the data analytics module.

Identity management module 204 is a module that associates users and their login credentials with social networks to enable platform 200 to post content on such networks. Identity management module 204 communicates with user account database 214 and content database 216.

Content discovery module 206 is a module for discovering content that is used as recommendations for posting. The content is associated with topics that may be of interest to the user's audience members. Content discovery may be achieved in several ways. Klout, Inc. (Owned by Lithium Technologies, Inc.) offers a platform for content discovery. Content discovery may be achieved by employing the technology described in U.S. patent application Ser. No. 14/702,696, filed May 2, 2015, entitled “System and Method of Providing a Content Discovery Platform For Optimizing Social Network Engagements,” which is incorporated by reference herein. With the platform described in that application, the platform collects social media data, RSS feeds and articles, creates URL summarization documents from the collected data, creates features for capturing different aspect of an article's relevance using machine learning and trains models on subsets of articles to determine the weights for each feature. Models may be trained with different objectives. For example, the models may be trained to optimize for different social network user interactions such as favorites, likes, clicks, user shares, audience reactions etc. The described platform given topics scores the URL summarization documents (URLs) using the trained models and the top articles are retrieved in order of score (rank) and presented to the user. Topics may for which content is uncovered may be manually selected by user, or system can leverage automatically assigned topic of users expertise, or aggregate audience topic interest. Examples of topic generation is disclosed in U.S. patent application Ser. No. 14/627,151, filed Feb. 20, 2015, entitled “Domain Generic Large Scale Topic Expertise and Interest Mining Across Multiple Online Social Networks” which is incorporated by reference herein. Module 206 communicates with content database 216. Content discovery module 206 is described in more detail below. Also, content discovery may be tuned to brand owned content where data is sourced only by the brand owned web property some of which may include blogs, communities (e.g., via Lithium Technologies, Inc. Community Platforms) etc.

Scheduling module 208 is a module that functions to schedule to determine an optimal time to post content (e.g., a message) within a specified time period in order to maximize the probability of receiving reactions from audience members. This module also performs user personalized schedule generation (also known as auto-scheduling) including estimating audience reaction, domain specific schedule personalization (tuning) and user strategy for scheduling multiple posts. This is described in more detail below.

Security—authorization and approval module 210 is a module that functions to provide security layers or levels at different stages of the process of posting content. Module 210 for example enables a user to identify authorized users to approve and post content.

Data analytics engine module 212 is a module that functions to provide data metrics with those audience members that react to a user's posted content. For example, the data analytics engine may analyze all reactions for forecasting results.

User account database 214 is a database, as known to those skilled in the art, that stores user account credentials for platform 200 as well as social networks in which users desire to post content for audience member reaction.

Content database 216 is a database, as known to those skilled in the art, for storing content generated by discovery module 206.

Schedule database 218 is a database, as known to those skilled in the art, for storing schedules generated by the scheduling module 208.

The databases described on one form of data storage but those skilled in the art know that any data storage or strategy other than a database be used for storing the data disclosed in this disclosure.

FIG. 3 depicts example high-level method steps for implementing the software modules shown in FIG. 2 . In particular, execution begins at step 300 wherein a user selected topic is received to create content for a user to post to one or more social networks. Execution proceeds to step 302 wherein content discovered relating to the selected topic is generated. Simultaneously (or alternatively), existing arbitrary content is received from the user at step 304. Now, regardless of the origination of content, execution proceeds to steps 306 and 308 wherein data day parts from the user are received for content posting on the one or more social network(s) and wherein selected social network(s) in which the user desired to paste content are received.

Next, once the content, day parts and social network selections are received from the user, execution proceeds to step 310 wherein a schedule for posting the selected content on the social networks is determined (by scheduling module 212). That is, the schedule is formulated to determine the optimal time to post content (e.g., a message) within a specified time period in order to maximize the probability of receiving reactions from audience members. Optionally, schedule determination may include estimating audience reaction (on one social network as a function of reaction on another), domain specific schedule personalization (tuning) and user strategy for scheduling multiple posts. This is described in more detail below. Execution proceeds to step 312 wherein the selected content as authorized by the user is posted on the social network(s). Following, the number of reactions (engagements) and the number of audience members that post such reactions are monitored (collected) at step 314 and analyzed (by data analytics engine 212). Metrics for such data are generated and displayed for the user to review. This is described in more detail below.

FIG. 4 depicts an example diagram illustrating salient flow to support the operation of platform 200. Along the top of FIG. 4 , a posting user is shown with a plurality of followers or connections (also referred to as audience or audience members) and individuals for whom the posting user is following. As known to those skilled in the art, the user posts content on social networks 104 and the user's audience (members) view and react to the posted content (audience member reactions). It then follows that a posting user is associated with his or her own user (data) graph (user graph) that comprises several sources of data including data relating to user followers (i.e. who is following the user in these social networks and (2) data relating to those past interactions with the user in a previous time frame on these social networks. Platform 200 employs collectors to collect the data from nodes relating to the interactions and user graphs including fetching, parsing and normalizing the data as known to those skilled in the art. Specifically, the data is collected and written to a cluster of nodes such as a Hadoop cluster that uses HDFS or other known to those skilled in the art as the file system, a data store such as HBase and an infrastructure such as Apache Hive or another known to those skilled in the art to process, query and manage the large datasets. Utilities such as Java functions to process user locations and time zones and operators and operators such as discrete convolution to process time-series vectors. The system allows proper mapping and ability to analyze billions content (i.e., messages) posted to social network platforms every day.

Platform 200 will process user (data) graph as user in-graph data and user out-graph data User out-graph data is data relating to those who follow a posting user and user in-graph is data relating to those following the posting user as known to those skilled in the art. With Facebook for example, the in-graph data and out-graph data are typically the same for followers known as “friends” but different for those following (use designated as a “like”) a specific Facebook branding pages like Nike's Facebook page.

Platform 200 will process the user graph data to generate a creation profile, a post to reaction profile and self reaction profile. For each posting user, a creation profile is created that represents the posts created by the user in each time bucket. As described below, a time bucket is short period of time (e.g., 15 minutes). The self reaction profile represents the user responses or reactions to the post that a user sees. The post to reaction (filter) profile (PTR(x)) represents a discrete probability distribution over the event that a reaction occurs within a time interval. Each of these three profiles are depicted below their respective blocks as graphs in FIG. 4 .

The user-out graph, post to reaction profile and reaction profile are used to generate or estimate a user schedule for posting content. The user schedule is essentially broken down into two types of schedules: first degree schedule for posting content and a second degree schedule for posting content. In order to distinguish between the two schedules, an example is in order. As part of a social graph as known to those skilled in the art, user u₀ for example has audience of other members a₁ so U_(out)(u₀)={a₀, a₁, . . . a_(m)}. So, when u₀ creates a post on social network (x), the post may be seen by potentially all audience members a_(i) of her audience. Now, a sample audience member a₀ of u₁ also belongs as an audience member of other users b_(i) and may view posts that are created by each of those users. This relationship between the users as U_(in) (b₀)={u₀, u₁, . . . u_(m)}. So, to derive the post schedule S(u₁) for user u₁, first degree schedule and a second degree schedule for posting content are two different approaches to calculating the expected number of reaction received from U_(out) (u₀) for a post created in the time bucket t.

This first degree schedule takes into account the reactions of u₀'s audience U_(out) (u₀), ignoring the second degree effects of the other posting users u_(i). The sum of delayed reactions per bucket t gives us the estimated audience reaction profile Q(u₀) for the user as described in more detail below, where the elements of the vector are given by:

${q_{k}\left( u_{0} \right)} = {\sum\limits_{j = 0}^{m}{r_{d,t}\left( a_{j} \right)}}$ where r_(d) is the delayed reaction profile R_(d) for an audience as described in detail below.

Thus in this case, the probability of receiving a reaction in any given time bucket t_(k)(u₀) can then be computed from the audience post reaction profile Q(u₀) as described in detail below. These probabilities determine the first degree reaction posting schedule S₁(u₀) as known to those skilled in the art.

The second degree schedule is estimated to account for cognitive overload of posts as depending on other user from which audience members are following. In short, a user desires that his/her post is visible to the audience for as long as possible. The second degree schedule is an estimate or function to account for that effect. The actions of the users u_(i) above represent the second degree effects for user u₀, since they affect how u₀'s first degree connection a₀ reacts to messages. To consider these second-degree effects, a second-degree reaction schedule S2(u ₀) is derived from knowledge of the time when the users u_(i) create posts, a time when a specific audience member b₀ reacts to the posts create by u_(i) and the probability that b₀ reacts to a post in a certain time bucket t. Second degree schedules are described in detail in “When-To-Post on Social Networks,” Spasojevic et al., Association For Computing Machinery 2015, which is incorporated by reference herein. Therefore it will not be discussed here. For now, these two posting schedules will be described as the user posting schedule for simplicity.

Now, with the user posting schedule along with the other calculated data, platform 200 will perform several functions including (1) estimating a user posting schedule on one social network based on the estimated schedule on another social network (2) domain specific personalization and (3) optimizing for multiple postings. The results of all of these functions are presented to the posting user through any system that incorporates platform 220 such as the Klout (from Lithium Technologies, Inc.) system. All of this is described in detail below.

(1) Estimating a User Posting Schedule on One Social Network Based on Estimated Schedule on Another Social Network.

As indicated above, find the best times personalized for the user to post content on social networks in order to increase audience member responses. Platform 200 formulates schedules for users to post content on these social networks based on user data relating to user behavior on those social networks to optimize audience reaction. However, data collection from private social networks (e.g., Facebook, Instagram etc.) may be difficult to achieve. Hence, the ability to estimate or calculate a schedule for posting content on a private social network on the basis of user data collected on a public social network (e.g., Twitter). FIG. 5A depicts example method steps performed by the scheduling module for estimating a particular user's posting schedule on a first social network (x) as a function of the user's posting schedule from another (second) social network (x). (Social networks (X) and (Y) in figures.) That is, the calculated function will enable a user to schedule posted content on the second social network based on data collected and subsequently analyzed from first social network (x) typically a public social network such as Twitter alone. Now, in order to calculate this function (as defined in step 512), platform 200 must first formulate posting schedules on the first and second social networks (y) and (x) for a sample set of users (typically large) and then the estimation can be achieved. In brief, this formulation takes into account user behavior in terms of post-to-reaction times and compares cross-network reaction behavior for users on the first and second networks.

Returning to FIG. 5A, execution begins at step 500 wherein data from social network (x) and social network (y) relating to the activities of a number of users_(N) are collected. (Note that access to and collection of a user activities are easily obtained or retrieved from public social networks such as Twitter without user authorization (i.e., user login credentials). Access and collection of a user's activities on private sites such as Facebook are authorized by the user to third-party platforms such as Klout or others as known to those skilled in the art.) Users_(N) may have one million or more users, but those skilled in the art know that any amount large enough to achieve desired results may be used for this method. These activities are user posts and reactions or responses to the user posts. Execution then proceeds to step 502 wherein users_(N) audience data associated with social network (x) and social network (y) is collected. The audience data associated with social network (x) and social network (y) includes (1) the user's followers (audience), i.e., who is following the user on these social networks and (2) past actions of the user, and 3) interactions among the user and the followers in a previous time frame on these social networks. The data is collected via an API or other interface as known to those skilled in the art.

Execution proceeds to step 504 wherein a post to reaction filters PTR (x) and PTR (y) for social network (x) and social network (y) are (estimated) determined by aggregating post to reaction times across (for any number of user) post responses from social network (x) and social network (y). The post to reaction filter PTR (x) of social network (x) for example is a vector with a value in each bucket as follows PTR(x)={ptr(x, b₀), ptr(x, b₁), . . . , ptr(x, b_(i)), . . . } where the value ptr(x, b_(i)) is the probability that a reaction occurs within at bucket bi after a post is posted in network x. ptr(x, b) is calculated by looking at time content (e.g., message) is posted and time of reaction. The difference (delta) is used to create a histogram or distribution function as known to those skilled in the art. One example is described in “When-To-Post on Social Networks,” Spasojevic et al., Association For Computing Machinery 2015, which is incorporated by reference herein.

-   -   A bucket (b) is a short period of time, i.e., 15 minutes, 1         hour.     -   T is a longer period of time (than a bucket), in which behavior         patterns may repeat and therefore can be generalized. It may be         a day, a week, month, year etc.     -   x represents social network, such as Twitter and Facebook.     -   T can then be divided into buckets and represented as (b₀, b₁, .         . . , b_(i), . . . ). For example, if T is a day and each bucket         is an hour, then b₀ represent the first hour of a day and b₂₃         represent the last hour of a day.     -   u is a user who posts in one or multiple networks.

PTR(y) is similarly determined as PTR(y)={ptr(y, b₀), ptr(y, b₁), . . . , ptr(y, b_(i)), . . . } with similar definitions except y is the social network (y).

Execution proceeds to 506 wherein self reaction profiles R(u,x) and R(u,y) for the users_(N) on social networks (x) and (y) are calculated by aggregating user audience member response (reaction) data. For example, given T, R(u,x) represents the self reaction profile of user u in social network x and R(u, x) represents a vector of values in each bucket as follows: R(u,x)={r(u,x,b ₀),r(u,x,b ₁), . . . ,r(u,x,b _(i)), . . . }

-   -   G(u, x) represent audience members of user u in network x.     -   a∈G(u, x) an audience of user u in network x.

R(u, y) is calculated using the similar vector and definitions. There is usually a time an audience member reaction is mapped into buckets. Thus, a specific post may be visible in one time bucket but may only be reacted upon in a later time bucket in R(u, x). The post to reaction filter PTR(x) function represents the lag in terms of a time interval d. Therefore a delayed reaction profile for a user is computed by performing a discrete convolution operation of the original reaction profile R(u,x) with the post to reaction filter function PTR(x) is as follows: R _(d)(u,x)=R(u,x)*PTR(x) where * is a discrete convolution function as known to those skilled in the art. See for example, “When-To-Post on Social Networks,” Spasojevic et al., Association For Computing Machinery 2015, which is incorporated by reference herein.

Execution proceeds to step 508 wherein the user_(N) audience post reaction profiles (data) Q(u, x) and Q(u, y) (also referred to as audience reaction profile) for social networks (x) and (y) are calculated. For example, for a given T, Q(u, x) is the audience post reaction profile for user u in network x and Q(u, x) has a vector of values, each of which is associated with each bucket b as follows: Q(u,x)={q(u,x,b ₀),q(u,x,b ₁), . . . ,q(u,x,b _(i)), . . . }

The value q(u, x, b) is the likelihood of an audience would respond to a post on social network (x) from user u posted at time bucket b_(i). q(u, x, b_(i)), is calculated by aggregating individuals as known to those skilled in the art. The aggregation appears as follows:

${q_{i}\left( {u,x,b_{i}} \right)} = {\sum\limits_{a \in {G{({u,x})}}}{r_{d}\left( {a,x,b_{i}} \right)}}$

One example is described in “When-To-Post on Social Networks,” Spasojevic et al., Association For Computing Machinery 2015. R_(d)(a, x)={r_(d)(a, x, b₀), r_(d)(a, x, b₁) . . . r_(d)(a, x, b_(i)) . . . }. R_(d)(a, x) is the delayed reaction profile for the audience.

Execution proceeds to step 510 wherein user_(N) posting schedule S(x, u) and S(y, u) for social networks (x) and (y) are generated. Once Q(u, x) is determined, a probability mass function can be determined which represents a post data schedule for the user. These probabilities can be computed as follows:

${s_{i}\left( {u,x,b_{i}} \right)} = {{q_{i}\left( {u,x,b_{i}} \right)}/{\sum\limits_{j = 1}^{N}{q_{j}\left( {u,x,b_{j}} \right)}}}$ The vector consisting of the probabilities determine the post schedule of the user. This vector is represented as S(x, u)={s₁(u, x, b₁), s₂(u, x, b₂), s₃(u, x, b₃) . . . s_(i)(u, x, b_(i)) . . . }. Once S(u, x) is obtained, the bucket with the highest value of S_(i)(u, x, b_(i)) is best time to post.

Execution proceeds to step 512 wherein a transformation function is estimated, based on the post to reaction filter data, self reaction profile data and the audience post reaction profile data, to transform the data underlying the schedule for posting content on social network (x) to data underlying the schedule for posting content on social network (y). In other words, the transformation function actually establishes or identifies a relationship between a schedule for posting content on social network (x) and a schedule for posting content on social network (Y). This is represented as S(y, u)=F(S(x, u)) where S(x, u) is the schedule for posting on social network (x) and S(y, u) is the schedule for posting on social network (y). At this point, a goal at this step is to create the function F that is necessary to transform the posting schedule for social network (x), i.e., transform the data underlying that schedule, into the schedule S(y, x) for posting on social network (y) for all users_(N). Step 512 may be accomplished in several ways. FIGS. 5B-D depict various ways or embodiments of executing this step as described below.

Now that the transformation function F has been established, any user “u” may apply it to a schedule for posting content on social network (x) to obtain the schedule for posting content on social network (y) as shown in step 514. This step 514 in effect estimates the schedule for posting content on social network (y) using the transformation function on the schedule data for posting content on social network (x). However, in order to apply step of 514 for a particular user, the basic steps 500-510 must first be executed to determine a schedule S(u, x) for posting content on network (x) for that particular user. This is represented by the dashed lines in FIG. 5A. Then, the schedule S(u, y) for posting content on social network (y) may be calculated for that particular user. This is described in greater detail below.

In one particular embodiment shown in FIG. 58 . In step 512-1, the transformation function F is created by applying a machine learning engine to the audience post reaction profile data Q(u, x) and Q(u, y) for the samples on both social networks (x) and (y). An exemplary regression method is linear regression as follows: S(u,y)=M*S(u,x)+B where M is a matrix and B are vectors and both are learned from the samples as known to those skilled in the art. Execution proceeds to several steps (similar to steps 500-510) including step 514 as described above (wherein the transformation function is applied etc.).

In yet another embodiment as shown in FIG. 5C, execution proceeds to step 512-3 wherein (any user) audience post reaction data profiles Q(u, x) and Q(u, y) (already calculated and stored) are retrieved for users_(N) with data to calculate the schedules for social networks (x) and (y). Execution then proceeds to step 512-4 wherein a transformation function for transforming the audience post reaction data profile Q(u, x) for social network (x) into audience post to reaction data profile Q(u, y) for social network (y). To achieve this, the machine learning engine applies to the audience post reaction data profiles from the social networks (x) and (y) to estimate this function F by applying a regression method as described above. Once the function F is determined, it is applied to the audience post reaction data profile Q(u, x) to obtain audience post reaction data profile Q(u, y) at step 512-5 and from that the schedule S(u, y) may be calculated form Q(u, y). Execution proceeds to several steps (similar to steps 500-510) including step 514 as described above (wherein the transformation function is applied etc.).

In yet another embodiment as shown in FIG. 5D, execution begins at step 512-7 wherein user audience post to reaction data profiles Q(u, x) and Q(u, y) for social networks (x) and (y) are retrieved for all users on such networks. Execution then proceeds to step 512-8 wherein a transformation function F is created to transform the audience post reaction profiles Q(u, x) for social networks (x) and (y) into the audience post reaction profile Q(u, y). Function F is computed by applying a machine learning engine to the audience reaction profile data Q(u, x) and Q(u, y) for a large sample of users of social networks (x) and (y). Execution proceeds to step 512-9 wherein the self reaction profile R(u, x) for social network (x) is retrieved and then the function F is applied to R(u, x) to compute (estimate) the self reaction profile on R(u, y). Once the self reaction profile R(u, y) is computed, a user audience post reaction profile Q(u, y) is computed as well as the user schedule S(u, y) is computed based on Q(u, y), R(u, y) as described above (not shown in FIG. 50 ). Execution proceeds to several steps (similar to steps 500-510) including step 514 as described above (wherein the transformation function is applied etc.).

Regardless of the embodiment used to estimate scheduling posts on social network (y), city, country and time zone-level schedules using platform 200 are aggregated. The time zones schedules may be used in the event there is insufficient data to generate a personalized schedule for the user.

As indicated above, any user “u” may apply the transformation function F (determined above) to a schedule for posting content on social network (x) to obtain the schedule for posting content on social network (y) as shown in step 514 in FIGS. 5A-5D. This step 514 in effect estimates the schedule for posting content on social network (y) using the transformation function on the schedule data for posting content on social network (x). However, in order to apply step of 514 for a particular user, the basic steps 500-510 must first be executed to determine a schedule S(u, x) for posting content on social network (x) for that particular user. Then, a schedule S(u, y) for posting content on social network (y) may be calculated for that particular user. An example of this appears below.

With the transformation function F in hand, a user such as Nike may desire to post content (e.g., articles) on the social network (y). Similar to step 500 in FIG. 5A, data is collected from social network (x) relating to the activities of Nike. Activities include Nike's (the user) posts and reactions or responses to the posts. Next, similar to step 502, data is collected that is associated with social network (x) relating to the number of Nike's audience. Next, similar to step 504, a post to reaction filter for social network (x) is determined. Then, similar to step 506, a self reaction profile is calculated for Nike (user) by aggregating Nike's audience response data. Now, similar to step 508, Nike's audience post reaction profile for social network (x) is calculated. Then, similar to step 510, Nike's schedule for posting content on social network (x) is generated. Now, in order for Nike to obtain a schedule for posting content on social network (y), the transformation function F (computed in FIG. 5A) is applied to the data underlying Nike's schedule for posting the content on social network (x) to transform that data into the schedule data for posting the content on social network (y). This is step 514 above.

(2) Domain Specific Schedule Optimization.

The schedules discussed above result in schedule personalization based on affinities of a user's audience members. However, personalization based on a user's audience member's characteristics can be generalized further. User interests and expertise with respect to topics may be generated as known to those skilled in the art. Now, platform 200 may also generate optimal schedules for users based on a mixture of topics or other domains, which may be derived from content being posted, the cumulative audience interest and/or poster's expertise, to elicit maximal reactions. This approach may work well where a lot of content reacted upon may not come from a first degree network but though discovery feeds on social networks. It is the domain, i.e., the nature of the post, that predicts potential audience behavior. FIGS. 6A-6B depict flow diagrams illustrating example method steps for generating a domain-specific post schedule for a user's audience (that is implementing the scheduling module 208 of platform 200).

Execution begins at step 600 wherein data relating to all users' activities are collected from social network (x). The activities relate to users' interactions, i.e., posts and responses or reactions to those posts on social network (x). (The interactions are defined as time of post, time of reaction, author, actor, content, network and other meta data associated with interaction.) As indicated above, access to and collection of user activities are retrieved on both public social networks such as Twitter without user authorization and private social networks such as Facebook with user authorization (OAuth tokens) to platforms such as Klout or others as known to those skilled in the art.

Execution then proceeds to step 602 wherein the domain(s) are attributed to each user in network (x). The domain may be a topic, time zone, geo-location based item, city, state, country or language (e.g., English or Spanish) or other domain as known to those skilled in the art.

Next execution proceeds to step 604 wherein a post to reaction filter PTR(D, x) for network (x) per domain is calculated. As described above, for a time internal d, the PTR(x) is a discrete probably distribution over the event that a reaction occurs within timed of creating a post on network (x). PTR (D, x) function is estimated to be the aggregating of the reaction times across all observed posts and reactions in network (x), domain (D).

Execution proceeds to step 606 wherein a “domain” reaction profile R(D, x) is computed for all users of social network (x) by aggregating the reactions of users in a given domain. The “domain” reaction profile R(D, x) is similar to R(u, x) described above except that it does not involve the audience of user and their reactions, but the reactions in context of the domain (e.g., reactions to content within domain, or reactions by people interested in domain). However, the similar calculation above for R(u, x) described above applies here.

Execution proceeds to step 608 wherein the domain post reaction Q(D, x) is calculated based on R(D, x) and PTR(D, x). The calculation performed is similar to Q(u,x) the above. In brief, a delayed reaction profile R_(d)(D, x) is calculated as R_(d)(D, x)=R(D, x)*PTR(D, x) where * is the discrete convolution operator as described above. The relationship and calculation of Q(D, x) as a function of R_(d)(D, x) is described above so it will not be done here.

Now, execution proceeds to step 610 wherein a schedule for posting on the social network (x) is generated base on the domain post reaction profile Q(D, x) as described above. Hence, a user posting schedule is created for a domain. Steps 600-610 are continuously repeating as a batch during the operation of the platform 200.

Now, the flow steps in FIG. 6B are performed concurrently with the flow steps in FIG. 6A. Execution begins with step 612 wherein a content data item and other metadata are retrieved. A content data item may be an article, message or any other data item known to those skilled in the art.

Execution proceeds to step 614 wherein each and every domain are detected. A domain for example may be <sports>, <nightlife> etc. The domain may be auto-detected using a natural language processing (NLP) algorithm known to those skilled in the art. Alternatively, a domain may be selected by the posting user. For such detection, each data content item is analyzed for its metadata as described above (e.g., by subject matter) and a particular domain or more are detected. There may be one domain, e.g., a topic or several domains, e.g., cities.

Execution proceeds to step 616 wherein the schedules generated per domain in step 612 are fetched. The domain schedules are then combined at step 618. If there are schedules for more than one domain, the combination can be a simple schedule addition followed by normalization as known to those skilled in the art. For example, there may be a schedule for politics, sports and art, each having a particular waveform representing a posting schedule. These waveforms are added and then normalized. Then, execution proceeds to step 620 wherein a domain schedule is derived for the item. That is, a posting schedule for the particular item is generated.

(3) Optimizing for Multiple Posts.

If a user wishes to post several content items (e.g., messages), the user must be aware that posting multiple items could have a diminishing return on the posts, i.e., reduction in the number of reactions due to audience fatigue, if not timely (spaced) posted. For example, if Nike desired to post five messages within a day part, individual messages that appear in close proximity in time could lead to a reduction in reactions. Alternatively, the number of message may not be capable of posting within the day part if spaced too far apart. Accordingly, platform 200 will find an optimized time to post multiple content items (e.g., message or articles etc.).

FIG. 7 depicts a flow diagram illustrating example method steps for optimizing the scheduling of posting content items (that is implementing the scheduling module 208 of platform 200). Specifically, execution begins at step 700 wherein a schedule S for posting a content item and post to reaction time profiles PTR(t) are computed based on redefined buckets. In this instance, the buckets are redefined with greater granularity than before busing interpolation techniques on a bucket time graph as known to those skilled in the art. Initially, the buckets may be fifteen minute buckets. However, the redefined buckets may now be one minute buckets.

Execution proceeds to step 702 wherein an initial first schedule is selected. Step 702 may actually be incorporated into step 700 if desired. Simultaneously with respect to step 700, execution also proceeds to step 704 where a decay function is modeled. The decay function which represents function of fatigue of a content item with an audience member. Decay function could be derived in various ways or manually set to fit product needs, or user's expectation. In one implementation, decay values are calculated with the following decay function F_(γ):

${F\;\gamma} = \left\{ \begin{matrix} {{t \geq 0},{\gamma \cdot {{PTR}(t)}}} \\ {{t < 0},{\gamma \cdot {{PTR}\left( {- t} \right)}}} \end{matrix} \right.$ where (t=time) the post to reaction time PTR(t) is depicted in FIG. 8 . FIG. 8 depicts a graph of decay function expressed via post to reaction time function over time for used for optimizing the scheduling the posting of multiple content items. PTR is depicted as at different times after and before (negative values). The negative values of t can translation to posting in the past relative to time as known to those skilled in the art.

γ is shown in FIG. 8 at the apex PTR(t). They is essentially used as a weighting function to establish weighted post to reaction values. Execution proceeds to step 706 wherein the optimal times to post data content items are determined. Initially, the time to post for schedule S₀ is t₁ as shown in FIG. 9A. (FIGS. 9A-9F depict several graphs illustrating a series of revised schedules as a function of the previous postings.) The schedules are a prediction of reactions to posts.) From this, execution proceeds to step 708 wherein the schedule S₁ is recomputed as a function of the decay function and prior schedule S₀. This is represented as follows:

S_(j)(t) = S_(j − 1)(t) − F_(γ)(t − t_(j))  where  j = index  of  number  of  previous  posts ${F\;\gamma} = \left\{ \begin{matrix} {{t \geq 0},} & {\gamma \cdot {{PTR}(t)}} \\ {{t < 0},} & {\gamma \cdot {{PTR}\left( {- t} \right)}} \end{matrix} \right.$ as described above (in one implementation). Execution then returns to step 706 wherein an optimal time to post the next content item is determined. So, with the new schedule S₁ the time to post is selected at the highest point t₂ in the graph in FIG. 9B. This calculation loop continues and times to post are selected t₃, t₄, t₅, t₆ etc. for recomputed schedules S₂, S₃, S₄, S₅ etc. as shown in the graphs in FIGS. 9C-9F.

FIGS. 10-13 depict several screen shot representations of the platform for managing a campaign for publishing data content on social networks. In particular, FIG. 10 illustrates a part of the platform in which a user (posting user) is presented with options for content to post to the user's audience. A number of publishing campaign topics are presented as a list. A user may select one of several campaigns for posting content. In this example, “Blue Skies Initiative” is selected along with “discover” for discovering and viewing topics of content streams for example including sports and climate change that a user may select. FIG. 11 illustrates an example of screen in which the user has selected the days and day parts (time intervals) for posting content. In addition, FIG. 11 specifically illustrates a user selecting the specific social networks in which he/she wishes to post such content. In this instance, the user has selected several content items for posting midday for auto-scheduling using the platform algorithm and selected content to be posted at a specific time.

FIG. 12 is similar to FIG. 11 except that it illustrates a menu for selecting a day part for posting. FIG. 13 depicts a page of metrics subsequent to posting. The metrics produced provide information of interest to the user including number of engagements (reactions/actions) etc. to a particular posted content item.
